阅读下面的短文,然后按要求写一篇150词左右的英语短文。

Middle and high school days are both fun and busy. Students spend their days in class, listening to the interesting and sometimes boring words of the teacher. They spend the short breaks running, playing, and shouting happily before going back to the classroom again. But how should students spend their free time outside school?

In Western countries, it is common for students to have a part-time job after school and at weekends. Students can earn their own money and learn more about the “real world”. They enjoy the extra independence and money, and parents enjoy the quiet house. However, it seems that, in China, parents worry so much about their children’ studies that they would prefer to see their children spending most of their free time studying and preparing for all those exams.

It is natural for parents to feel that way, but I believe the answer lies in balance. Sometimes, Western school children work long hours after school to make money, and so they become too tired to listen in class or have no time for homework. But Chinese students spend so much time on their studies that all else becomes less important until they want that new MP4 player.

So, find a good and healthy balance! If you have a part-time job, you’ll be happy, and your parents will also be happy because you’re spending your hard-earned money and not theirs!
